I have a problem with a "numerical input" question.
I have set "decimal seperator" to "comma".
Numeric question has advanced settings value between 0 and 10 and "only integer" = no, "maximum characters" = 4.
When testing a value of 2,6 can be entered (2.6 can not be entered) but when going to the next page you can't proceed because LS says that question isn't answered correctly. Integer values are ok.

A couple of times when going back and forth in the survey(changing value to integer, leaving blank (non mandatory question)), it was possible to enter a value with comma but I can't pinpoint what was different then.
